Two were off by two edges (one because I memorized the edge cycle wrong, the other because I forgot that there was an edge flip) and the other was off by 4 edges and 4 corners so I think I messed up a move or something.

3/8 = DNF, [33:16.00, 23:35].
I was trying to do this one like Maskow - same memorization and refresh order, and same kind of hand motions. The results were bad, but it really wasn't a bad attempt - third cube off by 3 corners, fourth cube off by 3 edges, fifth cube off by 2 edges, sixth cube off by 3 corners, and eighth cube off by 4 corners and 3 edges. Maybe next time will go better.
